,China-made centrifugal industrial fans
Our centrifugal fans for electric arc furnace dust collection are specifically engineered to handle the extreme conditions in steelmaking processes. This series of fans is suitable for high-temperature flue gas extraction and dust removal systems, reliably capturing and transporting high concentrations of dust and corrosive fumes generated during electric arc furnace operation.
Featuring a heavy-duty structure, reinforced impellers, and wear-resistant linings, these fans withstand thermal stress, abrasive dust, and high-temperature impacts. Precision dynamically balanced rotating components ensure stable, low-vibration performance during continuous, all-weather industrial operation.
- Capable of outputting higher outlet pressure while providing more gas flow with lower noise
- Stable operation at higher media temperatures
- Flexible speed setting through different pulley diameters for optimal efficiency
- Motor sliding guides for easy belt tensioning to reduce energy loss
- Bearing housing with temperature and vibration sensor mounting positions
- Liquid lubricant system eliminates need for bearing housing opening
- Observation window for easy monitoring of lubricating oil quality and level
- Labyrinth mechanical seal with leak-proof design prevents oil leakage
- Annealed impeller eliminates internal welding stress, preventing creep and cracks
